Abstract

Bague (13) pour un roulement (11) à éléments roulants, caractérisée en ce que la bague comprend au moins une zone (25, 27) d'extension circonférentielle présentant une rigidité réduite relativement au reste de la bague. La ou chaque zone d'extension circonférentielle peut être plus mince que le reste de la bague, et peut en outre comprendre un trou ou une fente. Dans un mode de réalisation particulier et préféré, il y a deux telles zones d'extension circonférentielle, chacune s'étendant autour d'un arc d'approximativement 60 degrés dans la direction circonférentielle.
